| 摘 要： | 结合对历史资料的分析,研究了2009年11月热带地区一次强的热带大气季节内振荡(MJO)过程与11月我国东部大范围雨雪天气的可能联系,结果表明2009年11月强的MJO过程是我国东部大范围雨雪天气的一个重要的影响因子.MJO对流11月上中旬在印度洋地区异常活跃,尤其是MJO对流中心在第3位相(印度洋中东部)维持了9天(...

| Abstract: | Possible relationships between the MJO and a severe ice-snow weather process in November of 2009 in Eastern China were analyzed.Results showed that a strong MJO process was one of the strong impact factors.MJO convection was markedly active over the Indian Ocean,especially with the convection center maintaining nine days in phase 3 of MJO(the middle-east Indian Ocean) and just corresponding to two strongest ice-snow processes.Composites of MJO events showed that when the MJO convective center is located ove... |
